Fingerprint Lite API for agents
16-hex fingerprint of text via SHA-256 prefix. Call when you need short cache keys for agent content. Returns fingerprint hex for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Intent to transaction
One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
